Summary	0009925: Camp sites cause animal population explosions.
Description	Like it says on the tin, when building a site it seems like you get some animals that become histfigs for some reason and thus don't despawn when they usually would, so the game keeps on spawning new ones to replace them, which interact with the ones there, making them histfigs, new ones spawn, etc, etc, etc. Save with this done twice, I wasn't able to try a third construction because it climbs up to 6.3 GB of ram use, where before it was 1.3 GB > 3.4 GB > 5.3 GB > ran out at 6.3 GB I guess since I only have 8 GB and the entire ram use was 7.54 GB at that point. http://dffd.bay12games.com/file.php?id=12275 Game has my mods and is using the "no hell layer > volcano tubes behave weirdly" glitch so I could build in the caverns/under the collapsing magma, but that isn't responsible for the population explosions directly, as I've had it happen while building on surface sites with no cavern access as well.
Steps To Reproduce	This is harder to explain, but generally it seems like having animal populations see you/try to attack you when you initiate construction leads to them becoming histfigs, and passing along a contagious lag-plauge of histfigging.

So, here's the save: http://dffd.bay12games.com/file.php?id=12377 Now, a word of warning: DO NOT FAST TRAVEL IN TO THE CENTER OF THE SITE, YOU WILL EXPLODE YOUR COMPUTER! Mine ran out of ram at 6.1 with no sign of slowing, just getting close enough to see 5 of the 28 buildings in the center of the site sent usage up to 3.25 GB: http://i.imgur.com/rH7xXgJ.gif At a guess, that animation has the (modded to be cyan for that syndrome) sense creature icons for tens of thousands of dwarves, possibly approaching 50,000 in those five houses visible. The mead hall has 22 dorfs in it, the site export shows 28 others to house the rest of the population. Over the two years that I have been constructing camps and eradicating beasts, that site Tunnelabbey had a rather strange population explosion. 105: �dkulet, "Tunnelabbey", hamlet Owner: The Ordered Stake, dwarves Parent Civ: The Sculpted Rocks, dwarves lady: Cilob Wheeledstruck, dwarf 147 > 29710 > 236608 dwarves 50 horses 2 > 4 > 7 dogs 2 turkeys This is a 33x33 world, over a period from 499-01-01 to 501-01-01, the original total dwarven population was around 17,000. Additionally a dark fortress (ruled by elves apparently) had another unusual population explosion. 20: Stosb�bslusp, "Hatedropes", dark fortress Owner: The Gloss of Winter, elves Parent Civ: The Heather of Sweltering, elves administrator: Romimi Fragrantcurled, goblin 1715 > 1732 goblins 54 > 216 > 3456 raven men 403 > 1612 > 25792 polar bear men 30 cougar men 5 ostrich men 48 skunk men 61 elf visitors 1 goblin visitor 1 human visitor 8 goblin outcasts 42 elf outcasts The visitors/outcasts populations changed some over this period but just a couple either way as would be expected, unlike the 4x > 16x multiplication of the raven and polar bear man populations. I did not build a camp beside either of those sites, I haven't actually visited either directly until just recently after noticing the MASSIVE population jump in the world sites and pops export and then noticing I had overlooked it in the prior ones. I did build a cluster of campsites on the east-south-east section of the map near a hamlet which ended up with the regular campsite wildlife population explosion (it is called Failboat for this reason) but I do not know how or why that would have triggered the hamlet/dark fortress citizen pop explosions.
